Jack (left) and Chico (right) are best buds who are staying at MaxFund, an animal adoption center in Denver, Colorado, while waiting for their new family to come find them. Chico has no eyes, but according to MaxFund, he’s so clever that he can pull of tricks that many sighted dogs can’t master. But he relies on his friend Jack to help guide him through the world. The adoption center’s volunteer Kathy Kelly-Weston says that “they really don’t like being apart.”
